.'lb all whom 'it may concern:

Be it known that l, SAMUEL C. STICKNEY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Anticreepers for Railway-Rails, of which the following is a specification.

My invention relates to improvements in anti-creepers for railway rails, and has for its object to provide an improved and etlioientdevice for preventing the longitudinal creeping of rails under the thrust of passing trains, a device which is easily applied to the rail and which will grip the rail tighter the harder the thrust.

To this end the invention consists in the construction, combination and arrangement of artshereinafter described and claimed.

n the accompanying drawings forming part of this specification, Figure 1 is a top view of the anti-creeper in place upon a rail, the rail and tie being partly broken away, Fig. 2 is a side elevation of the same, Fig. 3 is a front elevation of the anti-Creeper with the rail in section, Fig. 4 is a horizontal section through the anti-Creeper on line y-y of Fig. 3, with the tie shown partly broken away, and Fig. 5 is a vertical section on line z--z of Fig. 3.

In the drawings is shown a railway rail A spiked in the usual way upon a cross tie B. The anti-Creeper consists of a single casting or forging comprising a body portion 2 adapted to extend transversely under the base 3 of the rail and having at one end a downwardly, forwardly and laterally extending arm 4 and at the other end a hook or clamp 5. The arm 4 terminates in a rounded bearing face 6 which is designed to abut and bear against the tie when the anticreeper is adjusted in position. The clamp or hook 5 is constructed to it over the edge of the rail base, and has on the forward part of its underside -a bearing' face 7 adapted to engage the top of the rail-base and coperate with the longitudinally alining bearing face 8 upon the rear part of the upper surface of the body portion of the anti-Creeper in gripping the rail-base when the anti-Creeper is tilted in a vertical plane, or, more strictly speaking, when it is rotated upon a-transverse horizontal axis, as by pressure upon the bearing face 6. At its opposite end, near the point of union with the arm 4, the body from the rail.

portion is formed with an upwardly extending lange 9 terminating in a rearwardly and inwardly extending lug or claw 10 adapted to fit over the rail-base to prevent the anti-creep'er from dropping The hook is formed on the forward portion of the inner side of its end wall or shank with an interior bearing face 11, which is adapted to coii'perate with the bearing 12 on the rear portion of the inner side of the fiange 9 to grip the rail-x base when the anti-Creeper is swung hori zontally, or, more strictly speaking, when it is rotated on an approximately verticalaxis toward the tie, as by pressure on the bearing face 6.

In use the anti-Creeper is adjusted to the rail by hooking the clamp or hook 5 over one edge of the rail-base and thrusting the arm 4 back so as to carry the lug or claw 10 over the opposite edge thereof, the earth or ballast below the rail and in front of the tie having been rst scooped out to permit of this being done. The anti-Creeper is then moved forwardly along the rail until the bearing face 6 on the arm 4 abuts against the tie, as shown in Figs. 1 and 2. The hook end of the anti-Creeper is then driven toward the tie until the staggered bearing faces 7 and 8 and 11 and 12 Grip the ra'Fl base between them. This will bring the anti-Creeper into a position where itextends diagonally under the rail with the clamp 5 nearer to the tie than the flange 9. In order thatthe thrust of the rail may be confined as far as possible to the bearing faces, the body portion of the anti-Creeper is cut away or depressed between the hook 5 and the flange 9 so as not to present an intermediate surface having frictional Contactl with the rail base. When the anti-Creeper has been adjusted to this position, as shown in Fig. 1, the rail base will be gripped between the staggered upper and lower bearing faces 7 and 8 at the hook end ofthe anti-Creeper and also between the staggered lateral bearing faces 11 and 12 at the sides. Now when the rail is thrust forward by a moving train, it will be held by these gripping bearing faces from sliding through or over the antl-4 creeper. The pressure' against the anti- Creeper will be greatest at the hook 'end where the rail-base is most firmly gripped, and this end, being farthest away from the bearing face 6 which bears against the'tie as a fulcrum will yield most to the forward pressure of the rail. As the bearing face 6 is much lower than the hook or clamp 5 the thrust of the rail will 'tilt the anti-Creeper slightly forward in an approximately vertical p ane, or rather upon an approximately horizontal axis, and cause the rail-base to be clamped or gripped the more tightly between the upper and lower bearing faces 7 and 8 as illustrated in Fig. 5; and, as the bearingv face 6 is projected out beyond the oppositel end of the anti-Creeper, the hookend will be swung forward horizontally (rotating upon a vertical axis) toward-the tie, whereby the ysides of the rail-base will be gripped the more tightly between the opposed side bearings 1l and 12, 'as illustrated inFig. 4. Thus, the greater the pressure eX- ert'ed by theI rail against the anti-creeper the more tightly will it become held and clamped therein, the tie forming always a solid abutment against which the anti- Creeper is fulcrumed.

Where the anti-Creeper is described as swinging in ahorizontal or vertical plane, or rotating upon a vertical or horizontal axis, the words vertical and horizontal are to be understood as meaning approximately vertical or approximately horizontal, as the case may be. v

It is particularly to be observed that the anti-creeper engages the rail at short pivotal bearing faces only, so that the thrust of the rail will be .exerted entirely to rotate the anti-Creeper, and these bearing faces are not long enough to interfere with the free turning of the anti-Creeper.

I claim as my invention:

1. An anti-Creeper formed of al single integral piece of metal comprising a body portion having at one end a hook constructed to' fit over one edge of a rail base, and at .the other end a flange adapted to abut against the other edge of the rail base, and an abutment'arni integral with the flange and ex-l tending downwardly, forwardly, and outwardly therefrom, said hook having alateral bearing face on the forward portion of the inner side of its shank and the flange having 'a lateral bearing face at its rear end, whereby the flange and the shank of said hook will engage the side edges of the rail base at said staggered bearing faces only, when the anti-Creeper is swung forwardly in a horizontal plane under the longitudinal thrust of the rail at the hook end, and the hook and body portion having cooperating upper and lower bearing faces adapted to grip the base 'of the railwhen the vanti- `Creeper is tilted in a Vertical plane.

2. An anti-Creeper formed of a single integral piece of metal comprising a body portion having at one end a hook constructed to fit over one edge of a rail base, and at the other end a flange adapted to abut against the other edge of the rail base, and an abutment arm integral with the flange and extending downwardly, forwardly and outwardly from the outer side thereof, the hook standing in advance of the flange, and the shank of the hook and the inner side of the flange having cooperating lateral bearing the flange, whereby the rail-base is gripped between the flange and the shank of the hook when the anti-Creeper is swung forwardly in a horizontal plane, and the hook and body portion being formed with staggered upper and lowerl bearing faces respectively, the upper bearing standing forwardly of the lower bearing, said bearing faces being adapted to grip the base of the rail when the anticreeper is tilted in 'a vertical plane under the longitudinal pressure of the rail.

3. An anti-Creeper comprising a body portion having at one end a hook constructed to fit over one edge of a rail-base and at the other end a flange adapted to abut against the other edge of the rail-base and a downwardly outwardly and forwardly projected arm adapted at its lower end to abut against a cross-tie, the hook standing in advance of the flange, whereby the rail-base isgripped between the flange and the shank of the hook when the anti-creeper is swung forwardly in a horizontal plane underthe longitudinal pressure of the rail at the hook-end, and the hook and body portion being formed with staggered upper and under bearing facesl` respectively, the upper bearing standing forwardly of the lower bearing. said bearing faces being adapted to grip the base, of the rail when the anti-Creeper is tilted in a vertical plane under the longitudinal pressure of the rail.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL C. STICKNEY.
